With free UI design kits it is possible to get inspiration and even kicks-start a webdesign or app project. The success of websites, web applications and mobile apps strongly depends on the look and feel and the usability of the user interface. These kits typically include nicely layered PSD files you can use directly or as a starting point for creating your own unique interface design. It is however also possible to find fully implemented admin templates and this is where you can really start to cut down delivery time. A great deal of these have responsive layouts and works well on mobile devices as well.

Many web and app projects start up with primary focus on developing the features and getting the server side code up and running. This means that the design of the client side is often not taken care of until later in the process and overall it is not given the focus needed to make it stand out and make users fall in love. User interface design should not be underestimated; it is not as easy and quick as many think to get it right. Just consider the effort Apple put into creating the minimalistic and extremely user friendly UI on the iPads.  With a sizable collection of UI design kits, you will be able to shortcut the process, find inspiration and even choose to reuse design elements as they are.

In this article, I have collected more than 75 useful free UI design kits you should grab today for your own collection. I hope you find the collection useful as I took a lot of time to build it! Please help me by sharing the article with people you know.
